Abstract

The invention provides a steam generation device (50) comprising a water infrastructure (100) comprising a water supply system (110) and a heating unit (120) for heating water to steam; and a container (200) containing an anti-scaling agent (201) connected to the water infrastructure (100), wherein the anti-scaling agent (201) comprises a sodium-calcium double salt of hydroxyethylidene-(1,2-disphonic acid) with chemical formula Nax-Cay-HEDP, x+2y being equal to 4. The benefit that consumers may be able to experience when applying the anti-scaling agent of the invention is the more effective calc- clean function and longer life time of device.
